A LOFAR RFI detection pipeline and its first results
A. R. Offringa, A. G. de Bruyn, S. Zaroubi +1
Radio astronomy is entering a new era with new and future radio observatories such as the Low Frequency Array and the Square Kilometer Array. We describe in detail an automated fla…
Power spectrum extraction for redshifted 21-cm epoch of reionization experiments: the LOFAR case
Geraint Harker, Saleem Zaroubi, Gianni Bernardi +13
One of the aims of the Low Frequency Array (LOFAR) Epoch of Reionization (EoR) project is to measure the power spectrum of variations in the intensity of redshifted 21-cm radiation…
Foregrounds for observations of the cosmological 21 cm line: II. Westerbork observations of the fields around 3C196 and the North Celestial Pole
G. Bernardi, A. G. de Bruyn, G. Harker +11
In the coming years a new insight into galaxy formation and the thermal history of the Universe is expected to come from the detection of the highly redshifted cosmological 21 cm l…
